Author rebuffs Trump's latest legal threat: 'What is he gonna do?'

President Donald Trump's threat on Tuesday to sue an author who has written four books about him appears to be all hot air.

Trump told reporters on Saturday that he would likely sue author Michael Wolff, who Trump alleged "conspired" with disgraced financier and convicted sex criminal Jeffrey Epstein to hurt Trump politically. Wolff has been highly critical of both Trump administrations and has revealed several disturbing facts about Trump's relationship with Epstein. The president doubled down on those threats against Wolff during a bill signing at the White House on Tuesday.

Wolff responded to Trump's threats in a new episode of "Inside Trump's Head," a podcast he co-hosts with Joanna Coles of The Daily Beast.

"He obviously has so much to hide," Wolff said. "But also, he can't sue me. What is he going to do? Is he going to sit for a deposition? Is he going to answer all of the questions that I would have the right to ask him about his relationship with Jeffrey Epstein?"

Last week, Trump's Department of Justice released more than 3 million new Epstein files, which set off a firestorm of debate about how the convicted sex criminal was able to rub shoulders with the world's wealthiest and most powerful people.

The files also brought to light that some Trump allies, including people in his second administration, have not been honest about their relationships with Epstein either. For instance, it was revealed that Commerce Secretary Howard Lutnick continued corresponding with Epstein years after he claimed to have cut off contact.
